Qualms - I have a few! • 2.5" x 2.5" sticker • Comes as a kiss-cut, easy to peel sticker on 3" x 3" branded backing • Designed by Olivia Mew • Made of durable, waterproof, weatherproof vinyl • Appropriate for outdoor use and top-rack dishwasher safe when applied to water bottles (as dishwasher settings vary, we do recommend hand-washing when possible to give your stickers their longest possible life!)
